USB Cup Warmer
To avoid cold tea, use this. Plug the warmer in, place your hot beverage onto it. Result: your drink stays warm for 30-60 minutes longer than normal.
I’ve been told that you need a cup with a very flat bottom as to get maximum contact with the device. Otherwise it doesn’t work very well.
I really don’t see where the market is for this, is there nothing China won’t manufacture?
